【摘要】 建筑火灾的计算机模拟是建筑防火性能化设计的重要组成部分,场模拟是建筑火灾计算机模拟的主要方法之一。在建筑火灾计算机模拟过程中求解区域的取法将直接影响计算结果的合理性,求解区域的选择涉及边界条件的处理,本文通过对求解区域选取的举例说明和探讨,以求科学地认识和理解其在火灾计算机模拟过程中的重要性。更多还原

【Abstract】 The numerical simulation of the building fires is the important component of the performance-based design in building fire protection design.The field modeling is one of the main approaches on the numerical simulation about the building fire.The selection of the computational domain directly involves the result error of the computation,even determines whether the result of calculation is plausible.The domain is studied and discussed in order to know and understand how to use correctly the field model in the performance-based design.更多还原
